Do you want to implement a "map" completely from scratch? It's possible, obvious. The most common and effective type of map is an "hash" map, that is a map based on an internal "hash table". So you must first understand (if you don't know), how an hash table works.
Beware that implementing a very "good", optimal hash table is not an easy task ..... if you accept medium/low performances or not so many sophistications ... just for your study or exercise, it's ok.

For other doubts, please ask. And explain for example what type of keys/values you want to handle (if it's a specific map) or if you want a more "general" map (and eventually if you want to use the Java 5 generics).
